行走部分

Electric trams have operated on Hong Kong Island since 1904. The Hongkong Tramways Limited operates nine overlapping routes on 13 kilometres of double track along the northern shore of Hong Kong Island between Kennedy Town and Shau Kei Wan, and about three kilometres of single track around Happy Valley.

If you will try to form a notion of yourself, of the sort of a something that you suspect to inhabit and partially to control your flesh and blood body, you will encounter a walking bundle of superfluities: and when you mentally have put aside the extraneous things—your garments and your members and your body, and your acquired habits and your appetites and your inherited traits and your prejudices, and all other appurtenances which considered separately you recognize to be no integral part of you,—there seems to remain in those pearl-colored brain-cells, wherein is your ultimate lair, very little save a faculty for receiving sensations, of which you know the larger portion to be illusory.

假如你试图构造出一个&你自己&的概念，构造出你觉得是在占据并部分控制你血肉之躯的这么一个东西的概念，那你就会遇上&一副行走着的皮囊&要你处理：你在脑海里会想着把这些与&你自己&无关的东西——衣裳、四肢、躯体、后天习惯、口味、先天特征、个人成见、以及分离之后你认为不是构成&你&所必需的其他部件——通通剔除出去，剩下珍珠般灰白色的脑细胞，就是&你&的老窝，但是残存其中的，除了知觉功能，好像就所剩无几了。而你知道，知觉又多半是虚幻之象。

Roadheader is a part profile tunnel boring machine which can excavate,convey rock blocks and walk by itself. It is very suitable to excavate soft-rock tunnel.

臂式掘进机是一种集开挖、装碴和自动行走于一体的部分断面隧道掘进机，它非常适用于软岩隧道的掘进。

In this system the motion controlling centers upon regulating the speed of wire feeding and movement of lead screw in each direction.Four motors separately drive the wire-feeding tape roll and the lead screw move respectively following their directions of X, Y, Z axis. If all the motors are controlled by 89C51 directly,it will rise great difficulty for software and hardware implementation. So the suggested solution is to combine the microcomputer with stepper motor driver and control of their motion.

在本系统中运动控制的关键即送丝与各丝杠移动的调节，由四个电机分别驱动X，Y，Z轴方向的丝杠行走以及送丝操作，运动控制部分如果用89C51直接驱动各电机则在软件和硬件实现上都比较困难的，所以选用单片机与步进电机驱动器结合起来控制它们的运动。

The MG700-WD mining machine is a kind of electricity drawing and high-power mining machine, this machine's fuselage is low, installation-power is large, all electric motor are fixed up horizontally, mechanical drive is all the transmission of gear, electric motor、walking case drive wheel package etc, can take from old pool side out, so the transmission is high in efficiency, easy to install and maintain.

For this purpose,the traveling mechanism of the billet transporting car is reformed in the study,and FEM is used for analyzing the parts strength of the traveling mechanism and the roller track.

对板坯横移车行走机构部分作了技术改造，并对其运输辊道的有关零件进行了有限元分析。

A group of scientists at Carnegie Mellon University in Pittsburgh, Pennsylvania, studied insects like water striders and then built a small robot using ultra-lightweight carbon fiber that is also able to walk on water. But they still have some improvements to make — they said the water strider is able to move about 20 times as fast.

宾州匹兹堡的卡内基美隆大学有一群科学家在研究水黾等昆虫的构造后，利用超轻的碳纤维制作了一个也能在水上行走的小型机器人，但他们仍有一些尚待改进的部分──他们表示，水黾在水面上移动的速度比这机器人快上约二十倍。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
